One day, nobody dies. All across the world, nobody dies. And then the next day, and the next, and the next, people keep ageing – they get hurt and sick – but they never die.

But this can’t be a natural event – someone’s got to be behind it. It’s a race against time as CIA agent Rex Matheson investigates a global conspiracy.
